166 CXLVIII. ORCHIDEE. (J. D. Hooker.) [ Habenaria. 
3-nerved; lip as long as the sepals, obscurely 3-nerved, narrowed from the base up- 
wards, terminal teeth acute, middle one longest.— The analysis of the dried flowers 
has been very difficult, and repeated many times; the capillary stamnodia long 
escaped detection. Resembles a small Spiranthes of the S. æstivalis type, with 
which it was confounded in Griffith’s Herbarium. 
IMPERFECTLY KNOWN SPECIES. 
H. AFFINIS, Don Prodr. 25; Lindl. Gen. & Sp. Orchid. is a small state of 
H. goodyeroides. . 
H. CARANJENSIS, Dalz, in Hook. Journ. Bot. ii. (1850) 262; Dalz. A Gibs. 
Bomb. Pl. 267; lower leaves somewhat rounded, upper oblong-lanceolate 3-nerved, 
bracts shorter than the ovary 3-nerved, flowers small, yellow, dorsal sepal rounded, 
petals half ovate obtuse, lip tripartite, midsegment oblong rather obtuse, lateral 
shorter cuneate truncate, spur clavate shorter than the ovary.—The Concan ; Island 
of Caranjah, Dalzell. 
H. GRACILIS, Coleb. im Hook. Exot. Fl. t. 195, a Silhet plant, figured and 
described by Colebrooke (in Hook. Ezot. Fl, and to which he attributes an 
articulated fibrous root. I know of no plant in this least like the figure. Lindley 
( Gen, & Sp. Orchid. 302) suggests its being possibly his Cæloglossum brevifolium 
(H. eubitalis, 8). It is possibly a bad drawing of H. peristyloides. 
H. Lopn, Reichb. f. in Linnea, xli. 50; leaf cuneately oblong ligulate 
acuminate, raceme 2 ft. lax-fld., bracts half as long as the pedicelled ovary 
oblong acuminate, dorsal sepal ovate apiculate cucullate 3-nerved, lateral triangular 
retrorse 3-nerved, petals linear faleate l-nerved, lip tripartite, lateral segments 
linear retrorse, midsegments twice as long linear obtusely acute, spur filiform shorter 
than |the pedicelled ovary tip clavate, anther erect emarginate, tubes ascending, 
staminodes triangular.— E. Indies, T. Lobb. Flowers rather larger than those ot 
H. leptoceras, Hook. Bot. Mag., t. 2726 (a Brazilian species). . 
H. LONGIBRACTEATA ; Hook. f. ; stem stout leafy 2-3 ft., leaves 6 by 3-4 in. 
linear-oblong acute margins thickened, bracts 2-3 in. narrowly linear-lanceolate 
finely acuminate, lip 3-partite, segments linear lateral shorter, spur short obtuse. 
Platanthera longibracteata, Lindl. in Wall. Cat. 7048; Gen & Sp. Orchid. 293.— 
Burma, on the banks of the Irawaddy at Seendya, Wallich. Wallich’s specimens 
are in very young bud only, and the description of the flowers taken from Lindley 
cannot be depended on. It is a noble species, and should be sought for in Burma. 
H. MODESTA, Dalz. in Hook, Journ. Bot. ii. (1850) 262; Dalz. A: Gibs. Bomb. Fi. 
267 ; stem leafy at the base, naked above, bracts half as long as the ovary, flowers 
greenish white, lip 3-fid, lateral divisions linear lanceolate free spreading, mid one 
shorter ovate obtuse cohering with the tips of the petals and upper sepal and con- 
cealing the column, spur filiform hardly clavate a little longer than the ovary.—The 
Concan, at Salsette, Dalzell. Description from Dalzell, who does not appear to have 
seen leaves; itis, perhaps, H. stenostachya. 
H. PELORIOIDES, Par. & Reichb.f. in Trans. Linn. Soc. xxx. 139, t. 27, f. ^; 
tall, robust, leaves ovate or oblong-lanceolate passing into copious sheaths, spike 
many-fid., bracts large equalling the ovary ciliolate, sepals subequal lanceolate 
acuminate, lip linear, spur 0. TENASSERIM; Amherst by the seaside, Parish. Stem 
a foot high. eaves 2-3 in., largest subradical; upper sheaths slender, passing 
into the bracts the lower of which are 14 in. long. Spike 2-3 in., many-fid. ; 
sepals 3 in. long, membranous; petals as long as the sepals, lanceolate, 1-nerved ; lip 
very narrow; anther-cells elongate, with very long erect tubes, stigmatic processes 
long. Capsule ł in., sessile, fusiform.—An anomalous plant, clearly a Peloria form. 
] have seen but one indifferent specimen, 
H. vxirLoRA, Don Prodr, 25. Platanthera uniflora, Lindl. Gen. & Sp. Orchid: 
. 2957 is probaby a state of H. triflora. 
107. DIPLOMERIS, Don. 
Terrestrial small 2-fld. and 1-9-leaved. Leaves ensiform or oblong.
